- 中文摘要: The kinetics and mechanisms of dissociation reactions of open-chain and macrocyclic tetraamine complexes of copper(II) in strongly acidic, aqueous media are reviewed. Possible pathways for cleavage of copper-nitrogen bonds, factors influencing the dissociation rates, and the factors affecting the relative importance of each of these possible pathways are discussed. The varied kinetic behavior of the most closely correlated open-chain and cyclic tetraamine complexes (namely (1,5,8,12- tetraazadodecane)copper(II), Cu(3,2,3-tet)/sup 2+/, and(1,4,8,11-tetraazacyclotetradecane)copper(II), Cu(cyclam)/sup 2+/) indicates that ligand cyclization has a very large influence upon the rate constants for dissociation of complexes.
